Application mea January 24, ma. serial No. 678,212'.

devices adapted-to su port awnings 1nA front of or over the win( ows, doors or storefronts ofva buildin ,and more particularly it relates to such evices that. are adapted by their form and` structure to fold auch awning, or permit it to be rolled on a. suitfr U able roller, whereby it may be stowed snugly adjacent to the wall of a building, and the object of my improvement is to provide a folding awning arm that shall be ada ted-to support an awnin that may ex teni outwardly from the walof a buildin when spread or unrolled, to a distance muc i greater in extent than will be the extent of the vertical distance occupied by such awning when it is folded or rolled back against the wall ot the building to which it 1s attached; and a further object of my improvement is to provide folding-arm supports that shall operate lwith little friction tot'old into a compact form, and` permit the fabric of the awning to he neatly rolled orrtolded to occupy little space adjacent to its` supporting` wall, and which shall he simple in constriwtion, durable and etticient in operation. l attain these objects by devices 4illustrated in the accompanyingr drawin s in whichigure 1 is a view ot my invention in `side elevation when extended to spread an awning, Fig. 2 is a view otl same in side elevation showingr the relative position of its parts as they would appear' at one, 4point. of their movement in the operation of folding it, Fig. S is a view in side elevation of the same` showing` the position of its parts when folded against its supporting wall, while Fig. 4 is a plan view ot saine on a reduced scale when extended to spread an awning.

liikc reference numerals indicate parts throughout the. drawings.

Refcrrinpr now to Fig. l of the drawings, 5 indicates the, wall ot a building to which is fastened a supporting bracket 6 from the upper end of which projects a lug 7 and from the lower end of which projects another lug 8. Hinged to such lower lug S like by a pivot 9 is a bar 10 while another bar 11 y is hinged to the u per lu'g by iv'ot 12. The end, of the Ear 10 dist-ant` roin the `pivot` 9' is hinged by pivot 14, to a. lug -13 which is riveted to a lever U16-by' a rivet 1,5, the 'shorter arin of the lvr 16 extending obliquely upward is cormectedl Iwith the outer end of the bar 11 by` a link 17 by means of pivots 18 and 19 respectively. The lon" er arm' ofI the lever 16 extending outward y from its pivot- 15 is attached eurely to a cross-bar 20A toA which nedsg'e of the fabric of an awning 21 is fastened,

such .awning 21 eiztending in an'inclined.

direction to a roller 22 which is incre clearly indicated in Fi 4, the roller" 22 being suitably mountet to rotate on' pivots 23 disposed within bearings provided in an outwardly projecting portion of a bracket 24 whose supporting base 25 is fastened to the Wall 5 `at a suitable distance above the lu 7 lon the supporting bracket 6. One` en of the roller 22 is shown as being rovided with a bevel gear-Wheel 2G ich is adapted to mesh with another bevel gearwheel 27 which is mounted upon the end of a vertical shaft 28, shown by i1,- fragmentary viewv in F 1, the upper end the shaft 28 bein journaled in al r0jecting arm 29 whic projects `from tie su porting base 25. Well known Sitahe means, not shown, may be rovided to conmunicate motion to the Siaft A28 Whrby the roller 22 may be turned toroll upon it the awning 21. ltlanifest-ljgvat the (rmmencement of the rolling of the awm'n 21 on to the roller 22, first, the bars 10 an l1 will swing upwardly by motion conveyed through the lever 16 and a continued upvward movement of the parts will cause t onter jointed ends ot' the bars 10 and 11 respectively to rise higher than the plane of'the awning 21 and the longer arm of the lever lt? to dip downwardly as illustrated in Fig. 2 where the various parts are shown in one of the positions they assume during the operation of rollingr the awning 2l on to the roller 22. L

Fig. 3 illustrates the positions of the'various parts of my invention when the awning v21 is disposed in convolutions around the roller 22. It will be observed that a large .proportion of the awning folding arm extends upwardly ahove the awning 21 when said awning 21 is rolled upon the roller 22 whereby all parts of the structure will be sons Astanding on the sidewalk in front of a window or door which is shaded by an awningoperated by my invention.

ig. 4 shows by a plan view, on a reduced scale, an awnin extended outwardly from Y. the wall 5 if a uilding by means of a pair of folding arms embodying in y invention.

lThe compact form into which may be disposed a. folding arm embodying my invention is duelargely to the action of the link r17 and the angular form of the lever 16. ASuch links 17 'the degree of angl mav be p e of the lever 16 may be varied as desired to suit varying conditions with respect to dimensions of the area to be protected by an awning. 1n some cases it may be desirable to fold an awning instead of rolling it on to a roller and in such an instance my invention may advantageously be used by connecting the cross-bar 20 with a cord or rope and extending suehfeord over a pulley suitably disposed and secured on the Wall of tlie building above the top of the bracket 6 and thus by pulling downwardly on sucli cord the various partsv of the folding arm would operate in the same manner that they would if the awning 21 should befrolled on to a roller 22 as described.

Modifications in the proportions and form of various parts of my invention may be made without departing from the spirit thereof.

What I claim is: -f/ Y 1. In a folding-arm of the class described, the combination with a roller mounted to revolve in suitably supported bearings and adapted to roll an awning thereon, of a pair of folding-arms, one of such pairof foldingarms being suitably supported beneath and adjacent to each 'end of said roller and each varied in length and Y folding-arm of said pair comprising a lower` bar and an upper-bar one end of each of which is hinged to a suitable support, an angular lever having a long arm and a short arm, a link connect-ing one end of such upl ,i per-bar with the end of the short aiin of said angular lever, while said angular lever I is hinged at -tlie junction of its two arms with an end of said lower-bar, and a crossbar connecting and extending between the ends of the long arms of the said levers of i the pair of folding-arms, said cross-bar being adapted to be fastened to an edge of an ,i awning. l 2. In a' folding awning-arm of tlie class .i described, the combination with a vertical i support adapted to be fastened to the wall of a building, of a lever ofiiiigulai' shape,

an arm swingingly hinged at one of its ends with the upper end portion of said support While its other end is connected by a link i with one end of one arm of said lever and a I second arm swingingly hinged at one of its ends to the lower end portion of said supli port while its other end is hinged to said tlever at the point of junction of the two arms'r of said lever.

3 In a folding awning-arm of the class described, the combination with suitable supports, of a lever, an arm swinginoly hinged at,v one of its ends with one of said supports while its other end is connected` by a link \.'tli one end of said lever, and a second arin swingingly hinged at one of its en'lS to I the other of said supports while its j end is hinged to said lever at a desired point. between the two ends of said lever.
